REMOVAL AND INSTALLATION









REMOVAL SERVICE POINT

[[A]] CRANKSHAFT REMOVAL

After removing the crankshaft with the crankshaft sensing ring attached, temporarily place it on a V-block to prevent teeth of the sensing ring from deforming.

NOTE:
If a tooth bends, be sure to replace the crankshaft sensing ring with a new one.

INSTALLATION SERVICE POINTS

]]A[[ CRANKSHAFT SENSING RING INSTALLATION





Tighten crankshaft sensing ring bolts to the specified torque in the tightening order shown in the illustration.
Specified torque: 11± 1Nm (98± 8 in-lb)


]]B[[ THRUST BEARING INSTALLATION

1. Install the thrust bearing on the No. 3 bearing on the cylinder block side. Application of engine oil makes the installation easier.





2. Install the thrust bearing so that the grooved side is on the crankshaft weight side.

]]C[[ CRANKSHAFT BEARING UPPER INSTALLATION





1. When replacing the crankshaft bearing upper, select a bearing with the size corresponding to the cylinder block journal diameter in the table below.





2. The crankshaft bearing upper has an identification colour at the illustrated position.





3. Install the selected crankshaft bearing upper.

]]D[[ CRANKSHAFT BEARING LOWER INSTALLATION





1. When replacing the crankshaft bearing lower, select a bearing with the size corresponding to the crankshaft journal diameter in the table below.





2. The crankshaft bearing lower has an identification colour at the illustrated position.
3. Install the selected crankshaft bearing lower.






]]E[[ CRANKSHAFT BEARING CAP / CRANKSHAFT BEARING CAP BOLT INSTALLATION





1. Install the crankshaft bearing cap with reference to the identification mark as illustrated.





2. Before using the crankshaft bearing cap bolt again, carry out the check according to the following procedure:
(1) Measure the 2 points on the outside diameter of thread as shown in the illustration.
(2) When the difference between the measured outside diameters is beyond the limit value, replace the crankshaft bearing cap bolt.
Limit value

M10: 0.15 mm (0.006 inch)
M8: 0.10 mm (0.004 inch)
3. Apply engine oil to the threaded portion and seat surface of the bolt.
4. Tighten crankshaft bearing cap bolts to the specified torque according to the tightening order.
Specified torque

M10: 37.2± 2.0Nm (27± 1 ft-lb)
M8: 9.0± 2.0Nm (80± 17 in-lb)






5. Make a paint mark on the head of each bolt.
6. Make a paint mark on the bearing cap 90° from the paint mark made on the bolt, in the direction of tightening the bolt.
7.
CAUTION:

- When the tightening angle is smaller than the specified tightening angle, the appropriate tightening capacity cannot be secured.
- When the tightening angle is larger than the specified tightening angle, remove the bolt to start from the beginning again according to the procedure.

Turn each bolt 90° in the tightening sequence specified in step 1, and make sure that the paint marks on the bolt and cap are aligned.





8. Check end play of the crankshaft after installing the crankshaft bearing cap. If the end play exceeds the limit, replace the thrust bearing.
Standard value: 0.05 - 0.25 mm (0.002 - 0.010 inch)
Limit: 0.4 mm (0.02 inch)
